Optical circulator is something used to monitor the optical power traveling in optical fiber. Either it can be used to polarize lights flowing different directions into a single direction or light in the single director into several directions.
There are varieties of Polarization Insensitive Optical Circulators meant to serve different purposes. Choose an optical circulator based on what you want to achieve.
What is Optical Circulator?
Optical circulator is a non-reciprocal device used to allow the routing of light from one fiber to another, and this happens based on the direction of the propagation.
A special fiber optical component, optical circulator is used to separate optical signals in an optical fiber. It comes with three ports, and they are designed in a way that when light enters any port, it will exist from the next. This feature of high isolation of the input along others such as optical powers, low insertion loss, makes optical circulator a device widely used in a wide range of advanced communication systems and fiber optical sensing devices.
There are many manufacturers in China offering different types of optical circulators such as Polarization Insensitive Optical Circulator. If you are looking high quality circulators designed to your specific needs, and the best most competitive price, DK Photonics which offers a wide range of optical passive devices including the most widely used Polarization Insensitive Optical Circulator can be the right choice for you.

How to does the optical circulator work?
The Polarization Insensitive Optical Circulator which is used in fiber optical system directs the light/optical signals from one port to another. This helps prevent the signals transmitting in undesired direction. In a circulator which has three ports, signal is pushed from one port to the second port, and the another signal is directed from the port second to port 3 and at last, a third signal is transmitted from the last port to again to the port one. This is how the circulator helps you control the light and direct the signals into desired direction.
